No, an air fryer generally does not use a lot of electricity, especially when compared to a conventional oven. For households across Ireland concerned about rising utility bills, an air fryer represents one of the most energy-efficient and cost-effective ways to cook small-to-medium meals. While it may draw a high wattage instantly (similar to a kettle), its efficient design and rapid cooking speeds mean the appliance runs for significantly less time, resulting in a lower overall energy consumption (kWh) and a smaller bill at the end of the month.
An air fryer is essentially a compact countertop fan oven.
While the name might suggest deep-fat frying, it actually uses a different, much healthier method of cooking.
Air fryers utilise high-speed convection technology.
Here’s a breakdown of how they operate and why they outpace an oven on the efficiency front:
Because air fryers use such a high wattage when they run, it’s easy to assume they are expensive to operate.

To understand the cost of running an air fryer in Ireland, we need to consider its power consumption (wattage) and the current unit price of electricity (cent per kilowatt-hour, or c/kWh).
Air fryers typically have a wattage between 800 W (0.8 kW) and 1,800 W (1.8 kW), though larger models can go up to 2,500 W.
For calculation purposes, let's use the widely referenced Electric Ireland standard 24-hour rate of approximately €0.3475 per kWh (34.75 c/kWh), inclusive of VAT, as a representative example of a standard urban rate in Ireland.
| Air Fryer Size (Wattage) | Kilowatt (kW) | Approximate Cost for 15 Minutes (c) | Approximate Cost for 30 Minutes (c) | Approximate Cost per Hour (c/kWh) |
|---|---|---|---|---|
| Small (800 W) | 0.8 kW | 4.3 c | 8.7 c | 27.8 c |
| Medium (1,500 W) | 1.5 kW | 6.6 c | 13.1 c | 52.1 c |
| Large/Dual (2,500 W) | 2.5 kW | 10.9 c | 21.7 c | 86.9 c |
Note: Calculations are based on a unit rate of 34.75 c/kWh. Cost = (kW × hours used) × c/kWh rate.
As the table shows, a typical medium-sized air fryer (1,500 W) will cost you just over 13 cent for a half-hour cooking session.
This is where the financial benefit of the air fryer truly stands out.
A conventional electric oven typically has a much higher wattage, generally ranging from 2,000 W (2.0 kW) to 5,000 W (5.0 kW).
Let’s compare the cost of running a common 2,200 W (2.2 kW) electric oven versus the 1,500 W air fryer, using the same 34.75 c/kWh unit rate.
| Appliance | Power Rating (kW) | Total Time for Meal | Calculation (kW × hours × c/kWh) | Total Cost (c) |
|---|---|---|---|---|
| Electric Oven | 2.2 kW | 45 minutes (15 mins preheat + 30 mins cook) | 2.2 × 0.75 × 34.75 | 57.3 c |
| Air Fryer | 1.5 kW | 30 minutes (Minimal preheat + 30 mins cook) | 1.5 × 0.5 × 34.75 | 26.1 c |
As you can see, for a small-to-medium meal, the air fryer can be less than half the cost of using a traditional oven.
While the air fryer is inherently more efficient than a full oven, small changes in how you use it can lead to maximum savings on your monthly electricity bill:
While an air fryer beats a conventional oven on cost efficiency for small meals, it's important to see how it stacks up against other popular countertop appliances commonly found in Irish kitchens, such as microwaves and slow cookers:
| Appliance | Typical Wattage (W) | Core Function | Cost per Hour (c/kWh*) | Cost per Typical Meal (c) | Energy Efficiency Ranking |
|---|---|---|---|---|---|
| Air Fryer | 1,200 – 1,800 W | High-speed Convection Frying/Roasting | 41.7 - 62.6 c | 15 - 20 c (20-30 mins) | Mid-range |
| Microwave | 700 – 1,000 W | Reheating, Defrosting, Quick Cooking | 24.3 - 34.7 c | 4 - 8 c (5-10 mins) | Best for Quick Tasks |
| Slow Cooker | 75 – 300 W | Long, Low-Temperature Cooking | 2.6 - 10.4 c | 15 - 35 c (6-8 hours) | Best for Long Cooking |
| Electric Oven | 2,000 – 3,000 W | Large-Batch Roasting/Baking | 69.5 - 104.2 c | 55 - 75 c (45-60 mins) | Least Efficient |
It is worth noting that a modern **induction hob** is also very energy efficient for quick tasks like boiling water or pan-frying. The air fryer does not replace hob cooking, but rather provides an energy-efficient alternative to the full oven for roasting and achieving a crisp finish, a function the hob cannot easily replicate for the same energy cost.
*Note: Calculations are based on a representative Irish unit rate of 34.75 c/kWh (approximate, inclusive of VAT), and assume different usage times for each appliance to complete a standard meal.
Aside from the substantial savings on your electricity bill, air fryers offer a range of other compelling benefits that have led to their surge in popularity across Ireland.
The Irish market for air fryers is well-served by a range of popular brands known for quality and capacity.
Air fryers are now widely available and easy to purchase throughout the country.
For most Irish households, especially those cooking for one or two people or looking for a fast, healthier alternative to oven chips and small meals, the answer is a resounding yes.
While the initial purchase price might be higher than a microwave or a basic slow cooker, the significant energy savings, combined with the speed and health benefits, mean the appliance can quickly pay for itself over time. This includes reducing your electricity bills.
By reducing the kilowatt-hours you consume, the air fryer helps mitigate the impact of Ireland's high unit rates and the fixed costs like **standing charges** and the **PSO levy** that contribute to every bill.
An air fryer doesn't necessarily use less electricity than a kettle or a toaster, but it uses dramatically less overall energy for cooking a full meal compared to the most expensive appliance in your kitchen: the conventional oven.
By choosing a model that matches your cooking volume, you can ensure you’re making the most of this clever, cost-cutting appliance.
